The Doosan DX180LC-3 is a robust hydraulic excavator designed for medium to heavy-duty construction and earthmoving tasks. It is powered by a Doosan DL06K 6-cylinder, turbocharged, common rail diesel engine delivering 125 hp (93 kW) at 1950 rpm, featuring Stage IIIB emission compliance with exhaust gas recirculation (EGR) and diesel particulate filter (DPF) technology. This engine provides strong torque of approximately 332.7 lb-ft (450 Nm), supporting efficient hydraulic performance and faster cycle times while optimizing fuel consumption through an electronic power optimizing system (e-EPOS) and hydraulic power boost function. The excavator’s operating weight is 41,248 lbs (approximately 18,700 kg), offering a stable platform for effective digging operations. The DX180LC-3’s hydraulic system utilizes a cross-sensing pump with a maximum system pressure of around 350 kg/cm² (5,000 psi), enabling precise and powerful operation of the boom, arm, and bucket with digging forces of up to 10.7 tons at the bucket and 8.4 tons at the arm. It features multiple power and work modes to balance fuel efficiency and power needs, including power plus, standard, and economy modes. The operator benefits from a spacious cab equipped with a 7-inch color TFT LCD monitor for full access to machine settings and maintenance data, ergonomic controls with a jog shuttle switch, and enhanced visibility supported by rear cameras and large side mirrors. Dimensions vary with boom and stick configurations, but typical reach can exceed 29 feet with cutting heights nearing 30 feet. Fuel capacity is about 74 gallons, supporting extended operation times. Overall, the DX180LC-3 offers a combination of power, efficiency, and operator comfort optimized for diverse excavation requirements.
